[iRail] new betrains look&feel

[Louis de Decker]

Hi guys

thanks to Julien we have a wonderful new site template !
I've implemented it : http://www.betrains.com/
Small modifications :
     -home : I've added a mention about iRail/Julien's work and a 
contact option
     -the app icons lead to an individual information page instead of 
directly downloading the app

don't hesitate to shout if you have any feedback;.
good night !
Louis
